Security Light

This light will come on

This light will come on briefly when you turn the key toward START.

The light will stay on until the engine starts. If the light flashes, the Passlock® system has entered a tamper mode. If the vehicle fails to start.

If the light comes on continuously while driving and stays on, there may be a problem with the Passlock® system. Your vehicle will not be protected by Passlock®, and you should see your dealer.
